trying to choose rims for my '95 900se turbo but i'm having lots of difficulties because of rare bolt pattern 5x110mm most of the companies don't have any wheels that would fit that bolt pattern and the offset is different ...does anyone know some sites where i could get rims for my saab ...looking for 17" maybe 18"

You should also take a look at Turner's Hill Saab in England. There are a couple of interesting 17" wheels there that we don't get in the US and Canada, like the 17" "nail" wheels. Their address is http://www.turnershillsaab.co.uk

I didn't have any problems finding 18" wheels for my ng900. I looked at Antera, MilleMiglia, Speedline, TSW, OZ, Momo, ATP, ACE, Kahn, Kosei to name a few..After some hard thinking I went for 7,5*18" OZ Velas, got a really nice deal on them with Pirelli P7000 rubbers on
If I remember correctly Opel has the same bolt pattern as the ng900..That might be of some help also..

Thats the one Opel/Vauxhall stud pattern, any wheel maker that does wheels for 5 stud Omega/Vectra/Calibra/Cavalier [GM Opel/Vauxhall models] should have wheels to fit NG900 and classic 9-3, as the primary chassis components are based on the venerable Cavalier.
That 49mm offset is a headache though!

Yeah but the offset shouldn't be a problem...I was just asking around at the Saab TurboClub of Sweden about what the offset should/can be on 18/19" wheels on the ng900..And there was one guy who told me that he used 19" wheels with 235/35-19 tires and offset 35, this on a 3d..He said that it only in bigger bumps has he experienced rubbing at the back..So with 18" wheels and 225/40-18 tires and offset 35 it should not cause any trouble...
